Description:

Mountain pine beetle populations developed to epidemic level in
lodgepole pine stands in 1973. Approximately 426,355 trees were
killed on 3,433 hectares in 1976. Infestations are expected to
intensify in areas of current infestation and develop in uninfested
stands. It is predicted that 1,722,288 trees will be
killed in 1977. Salvage logging of infested trees and silvicultural
management to reduce average stand diameter below 20.3
cm d.b.h. are recommended.
